GUIDE FOR ICE PLOIWSVAND MARKERS.

SPECIFICATION forming part of Letters Patent No. 287,428, dated October30, 1883.

' Application filed July 26, 1883. (No model.)

To aZZ whom it may concern Be it known thatl, FRANSZ J OSEPH FISCHER, ofHamilton, Butler county, Ohio, have invented certain new and usefulImprovements in Guides for Ice Flows and Markers,of which the followingis a specification.

This invention pertains to the arrangement of the guiding-blades of icemarkers and plows.

The invention relates to devices whereby the guide is adapted for useupon either side of the plow or marker, the guide being in realitydouble-ended; to devices for keeping the plow in side balance,regardless of the weight of the acting guide; to devices for throwingthe guide into action, and to devices for throwing the guides out ofinterference with the ice when deep plowing is to be done.

The invention will be understood from the following description, takenin connection with the accompanying drawings, in Which- Figure 1represents a side view of an iceplow embodying my improvements, one ofthe guide-arms being cut away; Fig. 2, a plan of the same, and Fig. 3 arear view in section on line a.

In the drawings, A represents an ordinary ice plow or (aside from theform of the teeth) marker; B B, a pair of pivot-lugs fixed to the beamof the plow, to support the guide-arms; O O, the guide-plates, one oneach side of the plow-line, at such distance as to give the proper widthbetween the new groove being .cut and the old groove, in which theguide,

whichever guide may be in action, travels; D D, the guide-arms, pivotedto the lugs B, and having the guide-plates secured to them; E, a shortsemi-cylindrical lever projecting at right angles from one of theguide-arms, over its pivot; F, a similar lever upon the other guide-arm,forming, in conjunction with the lever E, a cylindrical lever for bothguidearms; G, a slotted bolted connection for uniting and adjusting,with reference to each other, the two levers; H, a diagonally-slottedplate, whose slot engages the cylindrical double lever E F; I,cylindrical guide-stems for theplate II; J J, lugs fixed to theplow-beam, and forming bearings in which slides the stem I, and alsoserving, in the case of the rear one, as a pivoting-point for braces forthe guidearms; K, a connecting-rod from the rear end of stem I to aconvenient position to be reached contact with thecice.

by the hand of the plowman; L, a handle on the rear end of therod K; M,detents for the rod K, and N a slot in plate H, at the rear 5 end of andtransverse to the slot of that plate. The two guide-arms, with theirguide-plates, form a rigid balanced structure, supported upon the pivotsat B, the bolt at G rigidly uniting the two arms. The two arms are sorelated to each other, as shown in Fig. 3, that when one guide-platetheright one in this figureis seated in a groove in the ice, and

thus adapted to guide the plow, the other guide-platethe left one-willbe supported idly above the surface of the ice. The weight of the actingguide is thus prevented from exerting any tipping tendency upon theplow. The guide structure being oscillated by the means shown, orotherwise, either guide-plate may be brought into action, and the guidethus caused to be upon the right or left side of the plow. Sliding theslotted plate H endwise will obviously oscillate the lever E F, and thusrock either guide into action. The means for sliding this platethe rodKand handle L-while not the only contrivances adapted to that end, willbe found simple and efficient. No stooping orleaning is required as theplowman effects the change in guides. The round stem I of the platepermits slight rotation of the plate, to compensate for the changingangularity of the lever E F while being shifted; but still sufficient.lost motion in the fit of the lever in the plate-slot is permissible, torender the rotation of the plate and the round stems I non-essential.

The plate H may be so set that the righthand guide is in the ice-groove,'or so that the left-hand guide is in the ice-groove, or so that bothguides will be idly supported a reasonable distance above the surface ofthe ice. For shallow work, only such adjustments are needed; and hencefor such work the entire guide structure may be formed in one rigidpiece capable of oscillating, as mentioned.

For very deep cutting, with both guides idle, the plow may be sunk sodeeply into the ice that the idle guides may form undesired Thus in Fig.3 the left hand guide may be up high enough for deep cutting by theplow; but when both guides are up and idle, they would only be up halfas high as the left-hand one in Fig. 3. I provide simple means forsecuring full elevation to both guides when both are idle. Such is theobject of the bolted connection at G, and the transverse slot N. In Fig.2, if the plate H be pushed clear forward, the righthand guide will belifted to its highest point and the left-h and guide dropped to itslowest point. The bolt at G is then to be loosened and the left guidelifted as high as the other guide. The slot at Gpermits the lever E toslide past the lever F into transverse slot N, after which the bolt isto be tightened. Both guides will then be supported idly, high up, anddeep plowing may be executed without interference from the guides.equivalent to the slot and bolt may be found suited to permit the twolevers to be divided and then secured.

. I claim as my invention v 1. In an .ice plow or marker, thecombination, substantially as set forth, of the plow or marker, apivoted lever balanced upon the same, guide-plates 011 the ends of saidlever, and means for securing the lever in different positions.

2. In an ice plow or marker, the combination, substantially as setforth, of plow or marker A, guide structure D D G O, balanced thereon,lever E F, formed with the guide structure, slotted pl ate H, rod K, andhandle L.

Other devices 3. In an ice plow or marker, the combination,substantially as set forth, of the plow or marker, a pair of guide-armspivoted thereto and projecting oppositely, guide-plates on the ends ofsaid arms, means for oscillating the two arms into different positionssimultaneously and securing them, and a bolted connection, as set forth,or its equivalent, for permitting the arms to be adjusted with referenceto each other.

4. The combination, substantially as set.
